Got stuck at installing pipenv for mac

when i try to install pip3 pipenv according to the Python course. i
got stuck it said " Requirement already satisfied “. But when i check the pipenv --version it says “Command not found”
Then i try to follow the instruction vi ~/.bash_profile. it shows something i dont understand”

>>> conda initialize >>>

!! Contents within this block are managed by ‘conda init’ !!

__conda_setup=“$(‘/Users/newimac/opt/anaconda3/bin/conda’ ‘shell.bash’ ‘hook’ 2> /dev/null)”
if [ $? -eq 0 ]; then
eval “$__conda_setup”
else
if [ -f “/Users/newimac/opt/anaconda3/etc/profile.d/conda.sh” ]; then
. “/Users/newimac/opt/anaconda3/etc/profile.d/conda.sh”
else
export PATH=“/Users/newimac/opt/anaconda3/bin:$PATH”
fi
fi
unset __conda_setup

<<< conda initialize <<<
